iron - Students | Britannica Kids | Homework Help

In the Earth, iron occurs mainly in iron-oxide ores. One of these ores is lodestone, or magnetite, named for its property of magnetism. Hematite is the most plentiful ore, but it contains less iron than magnetite. Limonite and siderite are less abundant ores of iron. Iron, alloyed with nickel, is also found in meteorites. (See also mineral.)

Iron Ore - an overview | ScienceDirect Topics

Three potential sources (from the ores, sinter, or scrap) of naturally occurring radionuclides in the slag are discussed. Iron ores due to their geochemical properties scavenge radionuclides and heavy metals resulting in only trace levels of uranium in the main raw materials for iron-making; iron ore and coke ranging of 20–30 Bq/kg and 5 Bq/kg for limestone (Cooper, 2005).

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
